Among the 50 most recent Science and Engineering rounds shown, the largest disclosed amount is Vietnam Airlines’ $2.9B on 2026-06-23. That $2.9B figure dwarfs the rest of the disclosed rounds: the next-largest disclosed amounts are PureCycle Technologies at $250M (2026-06-11) and Starfish Space at $112M (2026-04-07), while the remaining disclosed amounts generally sit far below $50M.
The list also clusters heavily in late June 2026: many entries land between 2026-06-02 and 2026-06-23, including multiple $2M–$25M rounds (for example, Dawn Aerospace $25M on 2026-06-16; Momentus $25M on 2026-06-12; Sicona Battery Technologies $31M on 2026-06-28). Stage and disclosure patterns are mixed: 5 rounds are labeled “undisclosed” amounts (including Syzygy Plasmonics on 2026-06-18 and OceanSmart.AI on 2026-06-04), and 31 of 50 rounds are tagged “Series Unknown”. By geography, the strongest repeating cluster is the UK in London (Delta Gold Technologies $190K on 2026-06-15; Zeabuz $4M on 2026-04-15; Groove Quantum $12M on 2026-04-30; plus Applied Atomics $4M on 2026-06-10).

Frequently asked
What stands out most in deal size across these recent Science and Engineering rounds?
Vietnam Airlines’ disclosed $2.9B on 2026-06-23 is the only round above $1B, with the next-largest disclosed amounts far lower—PureCycle Technologies at $250M (2026-06-11) and Starfish Space at $112M (2026-04-07).
Are there temporal clusters in the most recent batch of rounds?
Yes. A large share of entries fall in mid-to-late June 2026, including Dawn Aerospace ($25M on 2026-06-16), Momentus ($25M on 2026-06-12), Sicona Battery Technologies ($31M on 2026-06-28), and PureCycle Technologies ($250M on 2026-06-11).
Which disclosure pattern appears repeatedly: “undisclosed” amounts or “Series Unknown” stage labels?
“Series Unknown” dominates the stage field: 31 of 50 rows use “Series Unknown” (e.g., Syzygy Plasmonics on 2026-06-18; Magnax $41M on 2026-04-06). Separately, 5 rows show “undisclosed” amounts (e.g., OceanSmart.AI on 2026-06-04 and Inarcheck on 2026-05-15).
Is London or another city over-represented relative to other geographies?
London recurs multiple times in this set: Delta Gold Technologies (London) shows $190K on 2026-06-15, Applied Atomics (London) shows $4M on 2026-06-10, Groove Quantum is in Delft (not London), while Zeabuz is in Trondheim—so the London concentration is specifically around Applied Atomics ($4M, 2026-06-10), Delta Gold Technologies ($190K, 2026-06-15), and multiple other UK/European cities nearby rather than a single universal hub. (Other repeated locations include Vienna: GATE Space $7M on 2026-06-19 and Invisible-Light Labs $2M on 2026-06-09.)
Are there notable outliers besides the largest round?
Beyond the $2.9B Vietnam Airlines outlier, the list shows a low-end floor among disclosed amounts: Delta Gold Technologies at $190K on 2026-06-15 and Vertical Aerospace at $80K on 2026-02-03 anchor the bottom end. In contrast, several entries cluster in the mid-$10M to $50M band, such as Climeworks at $50M on 2026-04-28 and Magnax at $41M on 2026-04-06.
